The timing of ground limestone application to turfgrass areas within the northeastern United States is a critical factor influencing soil pH and nutrient availability. This process involves amending the soil with a material primarily composed of calcium carbonate or dolomitic limestone to neutralize acidity and increase pH levels. The target pH range for optimal turfgrass growth in this region typically falls between 6.0 and 7.0. Applying this amendment at the appropriate time maximizes its effectiveness in improving soil conditions.
Maintaining proper soil pH is crucial for several reasons. It optimizes the availability of essential nutrients for plant uptake, enhancing turfgrass health and vigor. Additionally, it can reduce the incidence of certain turfgrass diseases and improve the efficiency of fertilizer applications. Historically, lime application has been a standard practice in agriculture and horticulture to combat soil acidity, which is prevalent in the Northeast due to factors such as rainfall and acidic parent materials.
